THE BALLOON ANALOGY
The body of this article has been printed in the Physics Forum "Insights" blog and at the request of the forum owner, I have removed the body from this page so as to not cause the Physisc Forum to get a warning from Google that it has material that appears elsewhere. The body is now at:
The Balloon Analogy on PF

And here is an excellent discussion: Misconceptions About the Big Bang
A couple of other good ones:
a brief history of cosmology
--- two pages on your computer screen
a history of cosmology theories from the Greeks to now --- a considerably more extensive discussion
Sean Carroll's Cosmology Primer --- an extensive discussion
errors in some popular attacks on the big bang --- may dispel any misconceptions you might have
